ASTM B209 Aluminum Sheet
ASTM
B209 / 7075 aluminum is a 7000 series aluminum alloy: the prime alloying
addition is zinc & it is formulated for main forming into wrought products.
The properties of 7075 T6 aluminum include 17 general variations.
This page shows a summary range across all of them. The graph bars on the
material properties cards further compare 7075 T6 aluminum to
7000-series alloys (top), all aluminum alloys (middle), & the entire
database. A full bar means this is the highest value in the relevant set. A half-full
bar means it’s 50% of the highest, & so on.
About ASTM B209 Aluminum-
T6
temper 7075 has an ultimate tensile strength of 510–540
MPa (74,000–78,000 psi) & yield strength of at least 430–480 MPa
(63,000–69,000 psi). It has a failure elongation of 5–11%. Aluminum Alloy Sheet
is the most widely used form of Aluminum Alloy. It is commonly used for
construction, aerospace & defence applications. The T6 temper is usually
achieved by homogenizing the cast 7075 at 450 °C for several hours, quenching, &
then aging at 120 °C for 24 hours. This yields the peak strength of the 7075
alloys. The strength is derived mainly from finely dispersed eta & eta’
precipitates both within grains & along grain boundaries. Plus Metal
provides the best range of high-quality 7075
T6 Aluminum
Sheet in India.
Applications of ASTM B209
Aluminum
Due
to its high strength-to-weight ratio, aa7075 is used for highly stressed structural
parts. Applications of ASTM B209 aluminum sheet includes aircraft fittings,
fuse parts, meter shafts & gears, missile parts, regulating valve parts,
worm gears, keys, & various other commercial aircraft, aerospace &
defense equipment & components.
ASTM B209 Aluminum Fabrication
and Heat Treatment
·
Machinability ASTM
B209 Aluminum alloy can be machined in the annealed condition.
Oil lubricants are used for performing machining operations.
·
Forming ASTM
B209 Aluminum
alloy can be formed in the annealed condition. It can be warmed at 95 to 121°C
(201 to 249°F) if any trouble is encountered.
·
Welding ASTM
B209 Aluminum
alloy can be welded using a resistance welding method. The gas welding method
is not preferred for welding this alloy. Arc welding method should also be
avoided as it results in the degradation of corrosion resistance property of
this alloy.
·
Heat Treatment 7075 aluminum
alloy is annealed at (900°F) for 2 h followed by water quenching &
precipitation hardening heat treatment.
·
Forging ASTM
B209 Aluminum
alloy is forged at 372 to 483°C (700 to 900°F).
·
Hot Working ASTM
B209 Aluminum
alloy can be hot worked at 122°C (250°F)
·
Cold Working ASTM
B209 Aluminum
alloy can be cold worked using conventional methods in soft & annealed
conditions.
